Well, the title pretty much says it all...or does it? This may look like just a regular invitation picture, but all around the world, people are clamoring as to what the event will unveil. The past has shown that Apple likes to throw little hints in their invites, so perhaps there's more to these icons than what first glance shows us.

Most people immediately jump to the long-awaited iPhone 5, or possibly even the iPhone 4GS/4S, both of which make sense (the message does read "iPhone" at the bottom, after all). But considering there's only "one missed call", one would think that only one phone is being released.

Meanwhile, emphasis on the word "talk" may indicate voice-recognition services. Roughly 18 months ago, Apple acquired Siri, a start-up  that delivered voice-activated personal-assistance programs. This could be Apple's foray into voice-recognition.

No matter what gets unveiled though, there's no denying that Apple's simple invitation has garnered enough attention to keep folks interested until Oct. 4th.
